CATCHERS TABLE FOR ROLLING-MILLS.

SPECIFICATION forming part of Letters Patent No. 585,869, dated July 6,A1897'.

Application filed January 2l, 1897. Serial No. 620,089. (No model.)

To all whom, t may concern:

Be it known that I, SIGMUND V. I-I'UBER, a citizen of the United States,residing at Youngstown, in the county of Mahoning and State of Ohio,have invented or discovered certain new and useful Improvements inCatchers Tables for Rolling-Mills, of which improvements the followingisaspecification.

The invention described herein relates to certain improvements incatchers feed-tables for rolling-mills.

Vhen articles have been reduced to comparatively small sectional areasand elongated to a considerable extent, difficulty is frequentlyexperienced in feeding them into the rolls unless by an excessivemultiplication of the positively-driven rollers of the feed-table. Thisdifficulty arises from the fact that the weight of the article on eachfeed-roller, if the latter are spaced a considerable distance apart, issmall compared to the weight resting upon the aprons interposed betweenthe rollers. As above stated, this difliculty can be overcome byincreasing` the number of feed-rollers to such an extent that theportion of the article being rolled, resting upon the feed-rollers, willapproximately equal or exceed such portions as will rest upon theaprons. `Such multiplication of feed-rollersris undesirable on accountof the expense involved in their manufacture and maintenance. i t

The object of the present invention is to provide for the feeding ofsuch articles without employing a multiplicity of feed-rollers.

In geneial terms the invention consists in the construction andcombination substantially as hereinafter lnore fully described andclaimed.

In the accompanying drawings, forming a part of the specification,Figure l is a top plan view of my improved catchers table. Fig. 2 is aside elevation of same; and Fig.V 3 is a sectional elevation, the planeof section being indicated by the line III III, Fig. 2.

In the practice of my invention the feedtable consists of a rectangularframe formed of suitably-shaped metal beams and provided with suitablebearings secured on the side beams l for the feed-rollers 2. This frameis pivotally supported at or near its rear end upon blocks 3, which aresuitably anchored on the foundation of the table. At or near its frontend the table is provided on its under side witha block fl, adapted toform a bearingfor the outer ends of arms 5, which are preferablyprovided with frictionrollers 6. These arms are secured to a shaft7`,which also has an arm 8 keyed thereto, and is mounted in suitablebearings 9, as clearly shown in Fig. 2. The arm 8 is connected by a rod10 to a suitable operating mechanism, preferably to one employed forraising and lowering the rollers table on the opposite side of thereducing-rolls A, as clearly shown in an application iiled by meDecember 28, 1896, Serial No. 617,176. As the arm 8 is shifted to theright in Fig. 2 the table will be raised to the position shownin dottedlines for the purpose of feeding an article between the upper and middlerolls. This position will be hereinafter termed the feed7 position, andthe position shown in full lines will be termed the receiving position.

It will be observed that the feed-rollers 2 are arranged incomparatively close proximity at the front end of the table, but thattwo or more of such rollers donot extend across the table beyond thefourth feed-pass of the table. During the first three or four passes ofthe article through the rolls it will have sufficient size incross-section compared to its length that its weight will cause thefeed-rollers to take a sufficient bite to feed it into thereducing-rolls. After the fourth or fifth pass its elongation andconsequent transverse reduction will be such that the grip of therollers, being due entirely to the weight of the article thereon, willnot be suflicient to move the article longitudinally. In order toeffec-t a prompt longitudinal movement of the article under suchconditions, provision is made for increasing the bite of one or more ofthe rollers on the article. This increased bite is effected by means ofa loosely-running roller 11, mounted in suitable bearings in yokes 12,arranged in guides formed in the side bars l of the table.A These yokesare so arranged with relation to one of the feed-rollers 2 of the tablethat the idler 1l will have its axis in, or approximately in, the samevertical plane as that of the feed-roller, so that when the yokes aredepressed the idler ll will press the article with considerable forceagainst the IOO feed-roller. 'Ihe lower ends of the yokes 12 areconnected to arms 13, secured to the shaft 14, mounted in bearingssecured to the frame of the feed-table and having arms 15, also securedthereto, but extended in the opposite direction from the arms 13. To theouter ends of these arms are attached weights 16, whereby the yokes areheld up, supporting the idler out of operative position.

Any suitable means may be employed for pulling the yokes and theidler-roller to operative position, but it is preferred to employ thetable-lifting mechanism for that purpose, and, further, it is desirableto so proportion the connections between the yokes and their operatingmechanism that a quick movement will be imparted to the yokes and idleras the table reaches feed position. To this end the arm 8 of shaft 7 isconnected to a short arm t 17 on the shaft 14 by a rod 18. As with sucha construction a comparatively short movement of the arm 17 is requiredto shift the idler, and as it is desirable, as above stated, not toshift the idler -until the table is at or nearly at feed position, aslotted connection is formed between the arm 17 and rod 1S,which willpermit of the preliminary movement of the table without affecting theidler. l

In order to compensate for differences of thickness of the articlesbeing rolled, the bearings for the idler 11 in the yokes 12 areelongated and the journals of the idler are held against the lower endof such elongated bearings, but with a freedom of upward movement bysprings 19, interposed between the journalblocks 20 and the caps 21.pens in rolling long bars that the forward end thereof will curl or bendup to a greater or less extent, and in order to insure the entrance ofthe forward end of the bar between the idler and the feed-roller a hoodor deflectingshield 22 is arranged across the feed-table in front of thefeed mechanism, as clearly shown in Fig.. 2. l l

It will be readily understood by thoseskilled in the art thatcomparatively few positivelydriven feed-rollers need be employed betweenmy improved feed mechanism and the front end. of the table, for thereasonv that as soon as an article has been forced by such feed Itfrequently hap- 5 vfeed-table having one or more positivelydrivenfeed-rollers, an idler-roller yieldingly mechanism between thereducing-rolls and as soon as the latter have taken a bite they willdraw the article along without any assistance from the rollers of thefeed-table.

It will be observed that as the shaft carryy ing the arms which operatethe yokes 12 is mounted on the feed-table the vertical movements of thelatter will not affect the position of the idler-roller carried by theyokes.

I claim herein as my invention- 1. In a rolling-mill, the combination ofa feed-table having one or more positivelydriven feed-rollers, anidler-roller mounted in movable bearings above the feed-table, a

hood. or detlectingshield arranged transversely of the table in front ofthe idler, and means for moving the idler toward and from thefeed-table, substantially as set forth.

2. In a rolling-mill, the combination of a feed table having one or morepositivelydriven feed-rollers, means for raising and lowering thefeed-table, an idler-roller mounted in movable bearings above thefeed-table, a hood or detlectingshield arranged trans- I versely of thetable in front of the idler, and

means for moving the idler toward and from the feed-table, substantiallyas set forth.

3. In a rolling-mill, the combination of a `feed-table having one ormore positivelydriven feed-rollers, an idler-roller mounted in movablebearings above the feed-table, and means operative both for raising andlower- 3 ing the feed-table and for moving the idler i toward and fromthe feed-table, substantially as set forth.

4. In a rolling-mill, the combination of a mounted in movable bearingsnormally supporting the idler in inoperative position above forth.

In testimony whereof I have hereuntoy set my hand.
